To all whom it may concern.-

Be it known that LWILLIAM H. Mounnousn, a citizen of the United States,re siding at Pasadena, in the .county of Los,

Angeles and State of California, have invented new and usefulImprovements in Light-Ray Regulators, of which the followin is aspecification. l

J his invention lator.

It. is the principal object of this invention to provide a device whichmay be readily interposed between the source of light and lens withinautomobile headlights and which will bend the light rays in a manner toprevent them from roducing a glare and at the same time irecting themupon the roadway to produce a maximum amount of illumination withoutmaterially dimming the light. Other objects will appear hereinafter. Theinvention is illustrated, by way of example, in the accompanyingdrawings in which:

Figure 1 is a view in vertical section as seen through a headlight andparticularly discloses the manner in which the ray regulator ismounted.-

Fig. 2 is a view in front elevation illustrating the lamp with its lensremoved and the ray regulator in position.

Fig. 3 is a view in perspective illustrating one of the deflecting vanesas viewed relates to a light ray regu- 'from above.

Fig. 4 is a view similar to Fig. 3 illustrating one of the deflectingvanes as viewed from below.

Referring more particularly to the drawin 10 indicates the outer case'ofa headlig t within which is mounted a parabolic reflector 11. A lensframe 12 is securedover the front of the case and the reflector andsupports a lens glass 13. Mountedat the rear. of the reflector is anincandescent lamp 14 which is positioned within a socket 15 held by thecase 10 and throu h which it extends. It will be understood t at thedesign of the lamp is not essential to the present invention but thatthe ray regulator '16 is adapted to be operatively mounted uponheadlights of various types.

The ray regulator as here shown is formed of a series of equally-spacedhorizontallydisposed deflecting vanes 17 which are su- Speclflcation 01Letters Patent. Application filed September 24, 1917. Serial No.192,925.

periinposedone above the other and are mounted upon rods 18 and 19.These rods extend substantially vertical, being slightly Patented Aug.6, 1918.

inclined t'oward each other as they approach a mounting plate 20 at thetop of the regulator. This plate has an arcuate outer face whichconforms to the lens frame 12 within which it is held. The lower ends ofthe rods 18 and 19 are secured to the lowermostvane of the regulator.This vane in turn is secured to a lower mounting plate 21 by means ofbolts 22 and 23. This lower plate is angular in section and has a frontarcuate portion conforming to the frame 12 in the same manner as theplate 20. Brace wires 24 and 25 extend downwardly through openings 26and 27 in each vane. The vanes are so constructed that the metal punchedfrom the perforations 26 and 27 will form tangsl28 which extenddownwardly and space the vanes equal distances from each other. The

openings 29 at -the forward corners of the vanes through which the rods18 and 19 pass may also be formed with tangs 28 for spacing purposes.

Reference being had to the drawings it will be seen that the vanes areall of di en cut lengths and that some of them vary as to width as well.The length of the vanes is graduated from the lower vane to the top vanein uniform order. The length of the lower vane is substantially thelength of the cord of an are formed around the botin the lengths of thevanes is directly related to the curved surface of the reflector 11 sothat the side rays thrown from the reflector may pass through the lenswithout obstruction or deflection. It is manifest that these tom of thelens frame 12. The graduation rays will not produce a glare if theheadlight is properly set. 4 When considered in plan,

each of the vanes has ends which converge rearwardly to further preventobstruction of the side rays of light. As shown inlig.

1, the vanes are substantially the same width 1 damaging to pass/fromthe reflector without. obstruction.

.minate a distance from'the top thereof, said distance beingdeterminedby. the shape of the reflector to allow rays which are not Inoperation, the ray. regulator is mounted within the headlight asparticularly shown in Fig.1 and is held by the lens'which is positionedthereover. When the lamp 14 is lighted, its front rayswill assoutwardlybetween the vanes 17 while til will. fall upon the curvedsurface of the ref 7 their upper and lower faces,

Thelight from the headlight along the central portlon of the light beamwill passbetween the vanes vflected along a downward path of travelwithout glare. It will thus disclosed is decidedly simple in itsconstruc tion, may be easily mountedwithin head be seen that'the devicehere lights of ordinary. design, and will act effectively to regulatethe beam of light passing from the headlight.
